Application filed February 6, i922. Serial nassetssa To all whomit mayconcern: p Be it known that I, RICHARD LESTER WIL- ooX, a citizen of-theUnited States, residing at VVaterbury' in the countyof New Haven andState of onnecticut, have invented certain new and useful Improvementsin- Conipensating Mechanisms, of which'the following is a specification,reference being had therein to the accompanying drawings My inventionrelates to compensating mechanisms particularly as applied to a headingor upsetting machine, although not limited thereto.

- It is the object of this invention, among other things, to provide asimple'andeffe cient device, so assoc-iatedwi th the means for operatinga movablepart, sucha's the punch slide, that variations in the position.of movement thereof may be made without requiring adjustment ofitsoperating, means as has heretofore been necessary.

Among other aims and objects of theinvention maybe recited the provisionof a device of the character mentioned with a view to compactness and inwhich the number of parts are few, construction simple, and efiiciencyandoperation'hi'gh.

The details and arrangement of parts will be apparent from an inspectionof the accompanying drawings inconnection with the descriptionhereinafter contained and wherein a preferred embodimentnof theinvention is disclosed for the purpose of imparting an understandingofthe same.

In the drawings;

I Inoaxheaclingor'upsetting machine it has dried to be associated with beenthe practiceheretofore to operate the punch slide upon the reciprocatory gate from Ia rotatingshaft. Itis necessaryfrom time 7 to time to vary the relativeposition of the slide upon the gate,fthe means heretofore a provided forthis purpose requiring first, an

1 The punch slide 18, to which is"adjustab ly secured the punch block 19having the punches 2O fixed therein,- i s movably mounted in the frontend of the gate 11."

Slidably inountedi'n the cradle 17 is a shifter plate; 21 held therein,with proper frictional enga ement, by gibs 22 against which abut theadjusting screws 23. A, hinged connection is made between the punchslide 18 and the shifter plate 21 by a pin 24: that passes through thelugs 25 on the shifter plate and the lug 26 on the punch slide.

All of the parts above described are now known in the header art andrequire no further description herein.

The upper position of the slide in relation to the gate is limited bythe nuts 27 threaded on the stud 28 fixed in the gate 11, and passingthrough the lug 29 on said slide. Ttsdown position is limited by stopscrews 30 which are threaded through the 111. 529 and contact with thetop of the gate.

This method of adjustment ot the stroke and position of the punch slideis also old and the one always utilized by the operator, to the neglectfrequently of the adjustment ofthe slide operating mechanism, necessaryto fully accommodate the punch slide inits adjusted limits. I

My invention particularly relates to means for actuating the rock shaittwhereby any adjustment of the position of the punch slide 1S;throu u'hthe means above described is automatically compensated and taken.

care 0t, thus eliminating one adjustment.

necessary in the present type of heading or upsetting .n'iachines andthe one that is usually forgotten or overlooked by the operator withconsequent injury and damage to tie parts and ineffective and uncertainoperation.

In the practice of my invention I provide two compensating arms 31 and32, the former being either made integral with or secured to the rockshaft 18, and the otherrotatably mounted thereon. each being pro-q videdwith oppositely disposed lugs 33, these being arranged inpairs one abovethe other and through both of which pairs project the bolts 34:. Uponeach of these bolts is acompression spring 35. held and adjusted thereonto vary the tension thereof by the nuts 36. or the like.

when assembled there is an open space 37 between the adjacent faces of"each of the pairs of lugs 33 so as to permit relative movement.(lonm-wted with the compensah ing arm 2L is a crank arm within which astud 39 is radially adjustable by a screw lined in relation to the body10 and is of the usual structure. as well as the cam 45 or crank plateas is usual in headers.

The rotation of the cam 45 actuates the connection. arm as in thedirection 01"". its

length and thereby causes the compensating arm 32 tomove about its axisand through the bolts 34 and springs 35 similar movement is imparted tothe compensating arm 31 and the rock shaft 18.

As so arranged the adjustment of the parts and especially the springs,is such that they move as a unit until, the punch slide 1.8 has reachedthe limit of its stroke, either up or down. At this time thecompensating arm 31' comes toafull stop and: any additional moven'ientot the arm: 445

causes the compensating, arm 32 to rock in relation to the compensatingarm 31. This is permissible because one of the: springs will becompressed. The first portion of the reverse movement'ott the connectionarm a l actuates the compensating arm until the pressure of each of thesprings 35. is equal, when the two compensating arms again move as aunit.

fitthe limit of the up stroke the spring at the right oi Figure 1 iscompressed and the spring at the left at the limit of the dov" stroke.The extent of compressionot the springs is determined by the amount ofover-travel of the connection arm 44, which is designed to accommodatethe extreme limits of posit-ion; of the punch slide, or the position ofthe stud 39 in the crank arm 38.

In Figures 5 and 6 I have shown a construction wherein the feedmechanism may be actuated through the compensatingmechanism. In thisform the crank arm 38 is oi slightly dilierent shape and is providedwith a plurality of holes 49 therethrough to receive the pin 50 that isprojected through one end of a link 51 secured thereon by the screwwhereby a pivotal connection is made between said link and the rompensahlug arm. the opposite end oit'said linln by meansol a. pin 53?, beingw'muerted with the feed arm 54.

The feed mechanism adjacent to the link 51 is shown in Figure 5 bybroken lines, the same being of the usual form and constituting no partof this invention.

This modified form of mechanism operexactly as that shown in thepreceding figures with the exception that duringthe movement of thecrank arm 38, the feed mechanism is actuated through the link 51. Theseveral holes 4&9 in said arm permit the link 51 to be connected theretoat points varying in distance .t'ron: the axis. of the rock shaft 13,which provides for a variation in the length of the feed.
